A new lawsuit against Uber Technologies Inc. claims that the company may save more than half a billion dollars each year by misclassifying drivers in California as contractors rather than employees.

The lawsuit, brought on behalf of Studio City-based livery service Diva Limousine Ltd., claims that Uber’s “below-cost and anticompetitive pricing” has taken its toll on a proposed class of pre-arranged transportation companies in California and others across the country who have affiliate relationships with them.
